Description

The invention relates to a device for grinding and can be applied in the construction, chemical, metallurgical and other industries.

Closest to the present invention is a disintegrator comprising a housing in which disks with fingers located along concentric rows of l are mounted against each other on horizontal shafts.

The disadvantage of this disintegrator is its low efficiency.

The purpose of the invention is to increase the efficiency of the device by ensuring uniform wear of the fingers.

This goal is achieved by the fact that in a disintegrator comprising a body in which disks with fingers arranged in concentric rows are mounted against each other on horizontal shafts, each disk is made of composite rings, the rings being coaxially located relative to each other, and each of them has a gear ring that meshes with the gear, while the gears of two adjacent rings are connected by means of a gear wheel, the wheel of the first ring is connected to the shaft by a rigid kinematic connection, and the axes of all The shaft and gears are radially and rigidly connected to the body.

And there are several radial rows of wheels and gears at equal angles to each other.

In this case, a rigid kinematic connection with the shaft of the wheel of the ring of one of the discs is made in the form of a gear pair, the wheel of which is rigidly fixed on the shaft, and the wheel of the ring of the other disc is directly fixed on the drive shaft.

The drawing shows a kinematic diagram of a disintegrator.

The disintegrator comprises a housing 1 in which coaxially arranged input shafts 2 and 3 are mounted, on which gears 4 and 5 are rigidly fixed. Wheel 4 engages with wheel 5, which is connected to gear 6. The latter is connected on one side to the gear teeth ring 7, on which the fingers 8 are fixed, and on the other hand connected to the wheel 5, which is connected to gear 6, which is connected to the jogged BeHiioM of the subsequent ring 7. The engagement of the rims of the next rings is similar. The wheel 5, the gear 6 and the ring 7 with the ring gear form a repeating successive stage.

The opposite disk, consisting of a set of rings with fingers, is formed by steps and strikes the shaft 3 with wheel 5, which engages with gear 6, connected with the ring crown of ring 7 and with wheel 5 of the subsequent stage. The engagement of the rims of the subsequent rings is carried out in the same way. The wheels 5 and gears b are fixedly mounted on axles 9 and 10, which are mounted on housing 1. Ring 7. The first stage of the diagonal disk is mounted movably on the input shafts 2 and 3.

For the force unloading of the disintegrator, the wheels and gears are mounted at radial rows at equal angles to each other. Angles can make. 180, 120 and 90.

A counter movement of the rows of fingers 8 of opposite diagonal disks with equal linear speeds of the fingers in the second movement for the left and right disks (Fig. 1) is performed with the following ratio of wheel sizes:

From (2) and (3) the relationship between the velocities of the input shafts is.

 (4) The ring gear and ring gears 5 are made as external engagement.

Disintegrator works as follows.

From the input shaft 2 through the wheel 4, the movement is transmitted to the wheel 5 of the first stage, which rotates the toothed rim of the ring 7 and gear b, from the gear of the first stage b - wheel 5 of the second stage and gear b of the second stage, and from it to the ring of the ring 7 and the subsequent steps At the right dial disc, the movement from the input shaft 3 is transmitted to wheel 5, gear 6 of the first stage and from there to the ring of the first stage, then gear 6 transmits motion to subsequent stages m.

Thus, it is possible to organize counter-movement of rows of fingers with their identical and linear velocities in the rotational motion, which allows increasing the efficiency of the disintegrator by ensuring uniform wear of the fingers, reducing wear to a technologically reasonable minimum.
